The Formation Process Of Granite

Granite is a volcanic eruption of lava and is subjected to considerable pressure in the molten state to uplift to the crust surface of the tectonic rock. Some people think it is the result of the granite effect caused by the deep metamorphism and metasomatism.

Many non-ferrous minerals such as copper, lead, zinc, tungsten, tin, bismuth, molybdenum, precious metals such as gold, silver, rare metals such as niobium, tantalum, beryllium, radioactive elements such as uranium, thorium, etc., are related to granite. In the formation of the crust surface, the slow movement cools down. One of the igneous rocks is a substance formed by magma or lava cooled solidification crystals containing silicate (silicate) molten matter. When molten magma freezes and freezes, the minerals form in igneous rocks, such as olivine, or a stone. The most dense Fe-mg silicate minerals are formed at the highest magma temperature, and the less dense minerals, such as feldspar and quartz, are formed at the later stages of cooling. Minerals formed in lava can normally grow without restraint and have well-developed crystalline forms.

Due to its high hardness and durability, granite is the ideal material for the production of wall tiles and floor. Because granite is rarer than pottery or any other man-made material, paving granite floors can greatly increase the value of large houses. Granite varieties rich in color and diverse, can provide customers with a wide range of choices. Granite countertops are easy to maintain and have strong anti-pollution ability. Overall, granite floor tile can provide users with an extremely durable and easy to maintain surface. In addition, unlike man-made synthetic materials, natural granite countertops have a unique temperature resistance, so for all types of plate processing preferred. Natural stone of the United States joint stone, marble fireplace, marble.

A deep acidic igneous rock, belonging to igneous rocks. Commonly known as granite. The content of silicon dioxide is more than 70%. Block without bedding, mosaic structure, often spherical weathering. The color is lighter, to gray white, the meat red person is more common. Mainly by quartz (hardness 7), feldspar (hardness 6) and a small amount of biotite (hardness 2-4), such as dark-colored mineral composition. Quartz content of $number, alkaline feldspar more than plagioclase, about 2/3 of the total amount of feldspar. Alkaline feldspar is a variety of potash feldspar and sodium feldspar, plagioclase mainly for the longer stone or longer stone. Dark-colored minerals are mainly biotite, containing a small amount of amphibole. With a floral hillock structure or a patchy structure.
